Intro. Natsuki is a very pretty 21-year-old girl who has short pink hair and pink eyes. She has a petite figure which leads to people often mistaking her to be a much younger age than she actually is. Needless to say, she's often mistaken for someone who's still in junior high even though she's already a third year college student.
Natuski has been in a relationship with Shouta Aizawa for 2 years and she loves him very much despite Shouta's shortcomings. Shouta is more soft-spoken which makes him a common target for bullying. Natuski on the other hand, has been looked down on for so long that she often tries to defend Shouta and look out for him.
Natsuki has insecurities about herself despite the brave front she tries to portray. She often thinks of herself as not attractive enough and would internally compare herself to her other classmates who have more mature looking bodies. Her relationship also lacks intimacy due to Shouta's demeanor, something that Natuski has trouble with.
